Samsung has sent out media invites to a launch event on May 3 in London, where the company is expected to introduce its next flagship Android smartphone, dubbed the Galaxy S III. The invitation simply reads: "Come and meet the next Galaxy."  See also Samsung Galaxy S3 review.

Very little is known about Samsung's next Galaxy smartphone. The previous iterations, the Galaxy S and S II sold a cumulated 30 million, so the pressure is on for Samsung to deliver a killer device that would rival the sales of Apple's iPhone, which is also due a refresh, probably some time this summer. Visit Samsung Galaxy S3 launch: as it happened.

The typical online speculation on what the Galaxy S III will bring points to a larger screen, possibly 4.6-inch, bigger than the S II's but still below the Note's, and in line with the Galaxy Nexus. You could also expect a quad-core processor, 4G connectivity, a high-resolution camera, something up to 12 megapixels, and Android 4.0 on board. Go to Samsung Galaxy S3 specs and pictures.

The invitation to the Samsung event could also hint at what to expect from the S III. The paint-like blobs suggest the new phone could feature a S-Pen stylus, as found the Galaxy Note tablet/phone hybrid. Meanwhile, the brushed metal effect on the blue botch would indicate the S II could ditch the plastic case in favor of a metallic one.

Samsung said it will be broadcasting the event live on its official Facebook page.
